Um einen raschen Ablauf des Sorptionsprozesses sicherzustellen, ist vorgesehen, daß das Rohr (1) mit Rippen (2) versehen ist, die einen lichten Abstand (5) voneinander aufweisen, der geringfügig größer als die Korngröße der Granalien (4), z.B. eines Zeolithen ist, und der Raum zwischen den Rippen (2) mit einlagig eingebrachten Granalien (4) ausgefüllt ist, wobei die Rippen (2) zumindest im Bereich des äußeren Randes schräg nach oben verlaufen.Adsorber / desorber heat exchanger with a tube (1) surrounded by granules (4) and through which a heat-absorbing medium can flow. In order to ensure that the sorption process proceeds quickly, it is provided that the tube (1) is provided with fins (2) which have a clear distance (5) from one another which is slightly larger than the grain size of the granules (4), e.g. is a zeolite, and the space between the ribs (2) is filled with single-layer granules (4), the ribs (2) extending obliquely upwards at least in the region of the outer edge.
Description
Die Erfindung bezieht sich auf einen Adsorber-/Desorber-Wärmetauscher gemäß dem Oberbegriff des Anspruches 1.The invention relates to an adsorber / desorber heat exchanger according to the preamble of Claim 1.
Bei bekannten derartigen Adsorber-/Desorber-Wärmetauschern ist ein Rohr in Granalien eingebettet.In known adsorber / desorber heat exchangers, a tube is embedded in granules.
Bei solchen Wärmetauschern ergibt sich der Nachteil, daß aufgrund der schlechten Wärmeleitfähigkeit des Adsorbens und des hohen Diffusionswiderstandes innerhalb der Schüttung der Sorptionsprozeß nur sehr langsam und daher uneffektiv abläuft.The disadvantage of such heat exchangers is that due to the poor thermal conductivity of adsorbent and high diffusion resistance within the bed only the sorption process is very slow and therefore ineffective.
Ziel der Erfindung ist es, diesen Nachteil zu vermeiden und einen Adsober-/Desorber-Wärmetauscher der eingangs erwähnten Art vorzuschlagen, bei dem ein rascher Ablauf des Sorptionsprozeßes sichergestellt ist.The aim of the invention is to avoid this disadvantage and an adsorber / desorber heat exchanger to propose the type mentioned at the outset, in which the sorption process proceeds rapidly is ensured.
Erfindungsgemäß wird dies bei einem Wärmetauscher der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention in a heat exchanger of the type mentioned by characteristic features of claim 1 achieved.
Durch die vorgeschlagenen Maßnahmen wird erreicht, daß einerseits die Wärmetauschfläche des Rohres vergrößert wird und zwischen den einzelnen Rippen nur eine einlagige Schüttung möglich ist. Dadurch kann der Sorptionsprozeß trotz der schlechten Wärmeleitfähigkeit und trotz des großen Diffusionswiderstandes des Adsorbens wesentlich schneller und effektiver ablaufen. Dabei liegt eine große Stoffaustauschfläche für die Adsorption und Desorption des Adsorbats, z. B. Wasser, vor, und die Wärme kann durch den direkten Kontakt zur Rüppe schnell mit dem Wärmeträger, der im Rohr strömt, ausgetauscht werden.The proposed measures ensure that, on the one hand, the heat exchange surface of the Tube is enlarged and only a single-layer fill is possible between the individual ribs. This allows the sorption process despite the poor thermal conductivity and despite the large Diffusion resistance of the adsorbent run much faster and more effectively. There is one large mass transfer area for the adsorption and desorption of the adsorbate, e.g. B. water, before, and the Due to the direct contact to the scrub, heat can quickly be transferred to the heat transfer medium flowing in the tube. be replaced.
Dabei ist durch die vorgeschlagene Gestaltung der Rippen sichergestellt, daß die Granalien nicht von den Rippen fallen. Außerdem kann die Beladung der Rippen mit den Granalien sehr einfach erfolgen. Dabei können die Rippen in ihren Randbereichen mit einem nach oben abgewinkelten Rand versehen sein.It is ensured by the proposed design of the ribs that the granules are not fall off the ribs. In addition, the loading of the ribs with the granules can be carried out very easily. The ribs can have an upwardly angled edge in their edge areas his.
Im Hinblick auf eine besonders einfache Beladung der Rippen mit den Granalien ist es vorteilhaft, die Merkmale des Anspruches 2 vorzusehen.With regard to a particularly simple loading of the ribs with the granules, it is advantageous to Features of claim 2 provide.
Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:The invention will now be explained in more detail with reference to the drawing. Show:
Fig. 1 schematisch einen erfindungsgemäßen Wärmetauscher und Fig. 1 shows schematically a heat exchanger according to the invention and
Fig. 2 ein Detail einer weiteren Ausführungsform eines erfindungsgemäßen Wärmetauschers. Fig. 2 shows a detail of a further embodiment of a heat exchanger according to the invention.
Der dargestellte Adsorber-/Desorber-Wärmetauscher weist ein von einem wärmeaufnehmenden Medium durchströmbares Rohr 1 auf. Dieses Rohr 1 ist mit Rippen 2 versehen und steht mit diesen in einer gut wärmeleitenden Verbindung.The adsorber / desorber heat exchanger shown has a tube 1 through which a heat-absorbing medium can flow. This tube 1 is provided with ribs 2 and is in a good heat-conducting connection with them.
Zwischen den einzelnen Rippen 2 sind Granalien 4 in jeweils einer Lage eingebracht, wobei die Korngröße der Granalien geringfügig kleiner als der lichte Abstand 5 zweier Rippen 2 ist. Dadurch ist sichergestellt, daß sich zwischen je zwei Rippen 2 lediglich eine Lage von Granalien befindet, wobei es sich vorteilhafterweise um einen Zeolith handelt. Granules 4 are placed in each layer between the individual ribs 2 , the grain size of the granules being slightly smaller than the clear spacing 5 between two ribs 2 . This ensures that there is only one layer of granules between each two ribs 2 , which is advantageously a zeolite.
Die Rippen 2 sind bei der Ausführungsform nach der Fig. 1 mit einem schräg nach oben abgewinkelten Rand 3 versehen. Dadurch wird das Herausfallen der Granalien 4 verhindert.In the embodiment according to FIG. 1, the ribs 2 are provided with an edge 3 that is angled upwards. This prevents the granules 4 from falling out.
Bei der Ausführungsform nach der Fig. 2 sind die Rippen 2' trichterförmig ausgebildet und verlaufen in einem Winkel 6 zur Horizontalen radial schräg nach oben.In the embodiment according to FIG. 2, the ribs 2 'are funnel-shaped and run at an angle 6 to the horizontal, radially upwards.
